Answer:
7 millimeters
Step-by-step explanation:

Answer:
x=4
Step-by-step explanation:
since Y is 3x, then substitute the y with 3x which is 2*3x=5x and then plus the 5x which is 11x in total which equals to 44 (11x=44) then divide that you get: x=11.
Answer:
The exact value of 
Step-by-step explanation:
we know that
The angle
belong to the fourth quadrant
The function cosine is positive in the first and in the fourth quadrant
so

Remember that

so

<em>I think the best answer is:</em>
Explanation Below.
This is a proper fraction once the absolute value of the top number or numerator (4) is smaller than the absolute value of the bottom number or denomintor (52).
The fraction
can be reduced.
We will use the Greatest Common Factor (GCF) method to simplify it.
The GCF is the largest number between which two or more numbers can be divided evenly.
To find the GCF we list the the numerator and denominator factors (*) then we find the largest number that is repeated in both lists:
* The factors of 4 are 1,2,4;
* The factors of 52 are 1,2,4,13,26,52.
We can see that the GCD is 4 because it is the largest number by which 4 y 52 can be divided without leaving any residue.
To reduce this fraction, simply divide the numerator and denominator by 4 (the GCF).
So,

The factors are numbers that multiply each other to get another number. For example, 2 and 3 are factors of 6, because by multiplying them you get 6.
